(1)	The shares subject to the option vest in eight tranches over a ten-year term beginning on October 6, 2021, (the "Grant Date"), and ending on October 6, 2031, (i) if the closing price of Issuer's Class A Common Stock measured over any 30-consecutive-trading-day period equals or exceeds $90.00, $115.00, $145.00, $185.00, $225.00, $260.00, $300.00 or $340.00, respectively, and (ii) for the first four years following the Grant Date, subject to continued service as the Issuer's Chief Executive Officer as of the applicable vesting date, and thereafter subject to continued service for the Issuer as of the applicable vesting date as Chief Executive Officer or in another role to be determined by the board of directors.
(2)	The number of awards shown is at the highest level, with the target level being an aggregate of 16,000,000 shares; the actual number of shares of Class A Common Stock issuable upon vesting is subject to adjustment based on the greatest result of three tests tied to the stock price of the Issuer's Class A Common Stock relative to performance of the companies comprising the Nasdaq-100 Index as of the Grant Date, and may range from 80% to 120% of the target level (12,800,000 to 19,200,000 shares in the aggregate).
